Rotating at UT Houston is a good idea if you are interested in the program. But just be aware there are typically 7 or more rotating med students every month. So you will have to work extra hard to make a good impression and be remembered favorably. If you rotate at UT Houston, you will be given an interview - in the past, you interview at the end of the rotation with the Chair and PD, but I heard some rotaters came to interview day this past year.
I believe UT Houston is a very strong program and you come out a very competent medical dermatologist (I disagree with "namesname" info above). The pathology you will see is amazing. You will work at MD Anderson, #1 cancer center in USA, and see a lot of cancers (CTCL, melanomas, mets to skin, etc), GVHD, and drug reactions from chemotherapy and the new anti-cancer meds, etc. You will work at Harris County City Hospitals and see the great path from working with the indigent population. They also have a Derm-Rheum clinic and Bullous disorder clinic. The Derm surgery training is average. The program is weak in Peds Derm training and you do not get to work at a VA (Baylor has both Texas Childrens Hospital and VA).
UT Houston has 2 fellowships - Dermpath and Mohs Surg/Procedural Derm. The Dermpath fellowship training is 5 STARS (PD is Dr. Rapini) and I think it's the best of the 4 Dermpath programs in the Houston/Galveston area. There is a weekly Dermpath consensus conference with MD Anderson & Bayor Dermpath Fellowship programs where you can learn from other well-known DP Gurus.
Yes, you will have to deal with some scut, poor to average support staff, and work long hours, typically 8-6 or 8-7. But other programs (eg. Harvard and Penn) have just as long or longer working hours. However, working hard for 3 years of residency will make you a better doctor in the long run and you will appreciate your training when you are alone and have to make decisions on your own. Once you finish your residency, then you can choose your cush job and work 3 or 4-days a week.
That's my 2 cents,
